Improvement in manufacture of boxes, packages



UNITED STATES PATENT OFFICE HORACEV EVERETT, OF PHILADELPHIA, PENNSYLVANIA.

IMPROVEMENT |N MANUFACTURE oF Boxes, PAcKAGi-:s, ac.

Specification forming part of Letters Patent No. 47,532, dated May 2, 1865.

l plied to the formation of joints of boxes, cans,

or packages in the manner described herein-` after, the said joint being more rigid, strong, and less liable to break than those of the usual construction.

In order to enable others to practice my in vention, I will now proceed to describe the in anuer of carrying it into effect. j

On reference to the accompanying drawings, which form Aa part of this specification, Figure lis a sectional elevation of my improved joint, drawn to an enlarged scale, as used in the manufacture of tin boxes Fig. 2, a detached view of the strip which forms part of the joint; Fig. 3, the same joint as used in making cylindrical boxes; Fig. 4, the samejoint as applied to wooden or pasteboard boxes.

0n reference to Fig. l, A represents part, of the side, and B part ofthe top, of a tin box, and D is the strip of tin which forms part of the joint. The side A of the box terminates at the top in a plain ed ge,which is overlapped by the fold a of the strip D, the fold b of the saine be- Ving arranged for the reception of the lian ge d ofthe top B ot' the box. After the strip has been adjusted to the top and side of the boxit is soldered at the four corners, (marked 1, 2, 3, and 4.)

It will be evident that the sides as well as the top and bottom of abox, can, or package may be secured by joints y similar to that described, which are especially applicable to the manufacture of the tin vessels used for the Y transportation of petroleum, inasmuch as the corners are of great strength and are soldered at so many points that leakage is impossible. At the same time the rigid corners permit the box to be turned'over and over ou the ground without being subjected to injury. It will be i evident, too, that the strip ot itself affords the best medium for resisting weight imparted to the top ofthe boxa most important feature i when it is considered that cans or vessels for the transportation of petroleum are arranged one set above the other in layers, the lower i boxesbeing consequently subjected to apress-` ure of such severity that an ordinary joint is liable to become strained and leaky.

In Fig. 3, which represents a sectional plan ofrpart of a cylindrical box, the twoedges ot' the plate which forms the body of the box are connected together by a joint precisely similar to that described above. j

In Fig. 4 the cylindrical body of the box or package is made of pasteboard or Wood, the

tw oedges being connected together by a strip,

D, of character similar to that described above. By imparting a pressure to this strip in the direction of the arrows it is so tightly bound to the pasteboard or wood that the edges of the latter cannot be separated without the use of violence sufficient to destroy the pack-` age.

I claim as myinvention and desireto secure by Letters Patent- The bent strip I), applied tothe formation of the joints of boxes, packages, or other vesy sels, inthe manner described, for thepurposc specified. t

In testimony whereof I have signed my name to this specification in the presence of two Witnesses:

CHARLES E. FosTEn, JOHN WHITE.
